GLENDALE, Ariz. — NFL players have made it no secret they prefer playing on natural grass as opposed to synthetic turf. They'll get their wish in Super Bowl 57. NFL Field Surface Director Nick Pappas and his small group of specialists are getting the surface ready at State Farm Stadium for Sunday's game between the Kansas City Chiefs and Philadelphia Eagles. The home field of the Arizona Cardinals is unique in that the grass is on a giant, rolling track. Every day, the entire field is rolled outside of the retractable roof stadium, where it can get unobstructed access to Arizona's abundant sunshine. Then it can be rolled back inside for the chilly winter nights.
